J'IG FOR ASSEMBLING LOCOMOTIVE FRAMES.

Application filed April 6, 1922. Serial No. 550,015.

To all whom it may concern:

Be it known that we, JOHN P. SYKns and HARMON E. STOVER, citizens of the United States, residing, respectively, in Walhngford, Delaware County, Pennsylvanla, and Philadelphia, Pennsylvania, have invented certain Improvements in Jigs for Assembling Locomotive Frames, of which the following is a specification.

Our invention relates to certain improvements in jigs for assembling the frames of a locomotive so that, when the frames are brought in alignment and firmly secured to the jig, parts of the locomotive can be accurate'ly applied to the frames.

One'obj'ect of the present invention is to design the jig so that the frames can be supported at the openings for the journal boxes and the frames, with the parts attached thereto, can be removed bodily from the jigs when the cap plates of the frames are removed,

A further object of the invention is to extend the foundation plate from the saddles so that the jacks can be adjustably mounted on the plate.

In the accompanying drawings:

Fig. 11 is a sectional view on the line ll1l, Fig. 10. v

Referring to the drawings, 1 is the foundation plate extending substantially the full length of a locomotive frame, which is illust-rated at aa. 2 are saddles mounted .on the foundation plate. '3 are transverse base plates located at each end of the foundation plate in the present instance. Mounted on the base plates are jacks 4. These jacks support the overhanging ends of the locomotive frames. The foundation plate has two grooves 5 extending throughout its length and the saddles have projecting ribs, which extend into the grooves. The base 8 of each saddle is secured to the foundation plate by bolts 9, as clearly shown in Fig 3. The base plates 3 for the jacks have projections 7 adapted to the grooves 5 and are held in position bolts 10. By this construction, the saddles can be moved to any position desired on the foundation plate and the base plates 3 can also be moved to accommodate frames of different sizes. Each base late has a longitudinal groove 11 and the base 12 of each jack 4 has a projection '13 adapted to the grooves. In the present instance, the base plates have a series of cavities 14 in the bottom of the grooves 11 so that a pinch bar can be used to adjust the jacks in proper alignment with the frame. Each jack is provided with the usual screw 15 having a. swivel head 16. The screw can be turned to raise and lower the head, as desired.

The particular construction of the jack structure is claimed in an application for patent filed by us even date herewith.

The saddles 2 are made as shown in Figs, 3 to 6, inclusive. The standard 17 of the saddles is made solid and projects from the base 8 and is less in width than the space between the frames of the locomotive which are to be assembled on the saddles. Projecting from one end of each saddle is a bracket 18 and projecting from the opposite end of each saddle is a bracket 19. The b k 19 i of greater ng h than the bracket 18. These brackets are of such a size that they can extend through the journal bog: openings in the locomotive frames. the dot and dash line a, Figs. 3 and 4c, shows one of the largest frames and the dotted line 7) shows one of the smallest frames.

0n the bracket 18 of each saddle is a shoulder O. This shoulder forms an abutment for the frames at one side of the locomotive, irrespective of the size of the frame. This abutment is the guide for assembling all of the frames.

When a frame is mounted in position on the saddles 18. the straight pedestal c of the frame is forc d against the side 21 of the bracket by the screws 22 which is adjusted to fit against the opposite pedestal (Z of the frame, Fig. 2. Blocks may be used to fill the space, if the pedestals are spaced a considerable distance apart, This locks the frame rigidly in position. Then another frame is placed on the brackets 19 and spacingbars 23 are used to space the frames properly. and, when they are spaced, as shown by dotted lines, Fig. 3, they are held in position by the screws 24, which are similar to the screws 22. This screw may be located in any one of the three cavities 25 in the bracket 19, according to the distance apart of the frames of the locomotive being assembled.

Each bracket is chamfered at 26 to accommodate different fillets at the corner between a pedestal and the upper portion of the frame.

In order to secure the frame on the brackets 18 against the abutment 20 a clamp plate 27 is provided, held by a screw 28, Figs. 5, 10 and 11. and blocks 29 and 30 are adapted to channels in each bracket. These blocks press against the outside of the frame so that. on turning the screw 28, the frame is held firmly against the abutment 20. The spacing bars hold the other frame in proper position. The several parts of a locomotive are assembled on the frames, then the cap plates 6 are removed and the frames. with the parts attached. can be raised bodily clear of the saddles.

In some instances when a frame is of considerable length. an intermediate support 31 may be located on the foundation plate so to provide an intermediate support be tween the saddles. as shown clearly in Figs. 1 and 2.

It will be seen by the above construction. that the saddles and jacks can be located so as to support the frames of a locomotive properly, the saddles being adjusted so that their brackets will extend through the journal box openings formed by the pedestals of the frame. The side of the straight pedestal is used to align the first frame located on the brackets 18. This frame is held firmly in position against the shoulder 20 by clamps and against the side of the straightpedestal by screws 22. Then the other frame is properly aligned on the brackets 19 so as to be directly opposite the frame on the brackets 18. This frame is clamped in position by the screws 24:. Then the several parts of the locomotive can be assembled on these frames. after which the frames. with the assembled parts, can be bodily removed from the jigs by detaching the cap plates 6.
